SAW-TABLE .GAGE.

SPECIFICATION forming part of Letters Patent No. 271,408, dated January30, 1883.

Application filed April 13, 1882 (No model.)

Io all whom it may concern:

Be it known that I, JAMES RICHARD BREN- NAN, a citizen of the UnitedStates, residing at St. Joseph, in the county of Buchanan and State ofMissouri, have invented a new and useful Improvement in Saw-Table Gagesfor Sawing Miters, &(3., of which the following is a specitication. i

The object of my invention is to provide a cheap and simple sawingdevice, consistiug mainly of a saw-table, gage, and grooves, all soconstructed and arranged that miter-sawing may be eXpediLiously andaccurately performed, that lumber may be sawed atany desired angle, andthat all kinds ot' sawing, including cross-cut and rip sawing, may bedone at will. I attain this object by the nechanism as illustrated inthe arcompanyig drawings, in which- Figure l is a perspective View,showing the gage at an angle and the device ready for operation. Fig. 2is a detail view, showing how the gage is held securely in properposition. Fig. 3 is a detail view ot' the gage, and Fig. 4 is a detailview of the T-headed nut.'

Similarletters refer to similar parts throughout the several views.

A is what I call the saw-table. It has supports as shown, or it may besupported in any appropriate way. andit is made of wood or iron or anysuitable material. The table A is provided with three slots or grooves,a cut across it, and two slots'or grooves, a cut lengthwise of thetable, and connecting the center and left grooves a. The grooves a anda' may be of any number desired, and they are made, in their lower part,of a suitable slape for the receptio ot' the T-headed nut D, andsufficiently large, so that the nut D may move treely forward andbackward, and yetbe retained so as to hold the gage B in the properangle or position for sawing;

B is what ldesignate a gagei' *It is made ot' wood or iron, and ot' anydesired length. lt is narrow, long, and fiat, and' has extending almostits entire length the slot b, for the reception of the thumb-screw O.The shape and Construction of gage B is clearly shown in Fig. l of thedrawings.

C is a thumb-screw, provided with awasher or head, c. C rests or movesin the slot b of the gage B,and screws into the T-headed nut D, and isfor the purpose of holding the gage -B in any desired angle or position.

D is a T-headed nut, made as shown in Fig. 5 4,. being provided` with athread for the reception of the thumb-screw O. D slides or moves freelyin the slots or grooves a and a', which are made of a corresponding Tshape,

so that D can be retained, and yet move freely.

S is a saw, which does the ctting. A circular saw is shown in thedrawings; but any kind may be used, as desired.

Directly in front of the saw S, in the center 6 groove a, is a stop,f,against which the threaded nut D strikes to prevent the gage B fromstriking the saw when pushed forward, the gage B being cut away at e forthe same purpose. u

I have not deemed it essential for the purposes of my invention to showthe power attached for running the saw, as it is evident that the sawmay be run by either-steam or foot power. I have shown the saw S in the7 center groove a. The same may, however, be placed in any one of thegrooves or at the end of the table, no particular position of the sawbeing necessary for the objects of my in-' vention.

The operation is as follows: The gage B is placed on the table A in thedesired angle or position for cutting the miter or angle. Thethumb-screws G are screwed down into the T- headed nut D, therebyholding the gage B firmly at the desired angle or position. The wood tobe cut or sawed is placed on the table in front ot' the gege B,and thegage B is theu pushed forward (the nut D sliding in the grooves a) untilthe wood in front reac hes the saw and the miter or cut sawed asdesired.

Havingdescribed my invention, whatIclain as new, and desire to secure byLetters Patent, s-

The combination, with the table A, having 5 slots a a', and saw S,journaled in one of the transverse slots a, of the slotted gage B,having a notch, c, at or near the center of that edge earest the saw,the T-shaped nuts D, and thumb-screws C,adapted to hold the gage oo inplace, and the stop f, arranged in the transversc slots, substantiallyas described.

In testimony whereof [affixmy signature in presence of two witnesses.

JAMES RICHARD BRENNAN.
